1 Claim.

This invention appertains to new and useful improvements in pumps of thesubmerged type.

The principal object of the present invention is to provide a pumpespecially adapted for deep well submerged use.

Another important object of the invention is to provide a pump whereinthe plunger with its packing means can be readily removed from the pumpwithout disconnecting the pump from the tube line.

These and other important objects and advantages of the invention willbecome apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of the pump.

Figure 2 is a longitudinal sectional view through the pump.

Figure 3 is a cross sectional view.

Figure 4 is a side elevational view of the working barrel and flange.

Figure 5 is a bottom plan view of the shell top.

Figure 6 is a top plan view of the bottom of the shell.

Figure 7 is a top plan view of the socket screw.

Figure 8 is a section on the line 8-8 of Figure 2.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 4 represents the cylindrical shell which hasthe sleeve 5 extending upwardly from. its upper end and internallythreaded to receive the lower end of the reducer t which, in turn, isconnected to the lower end of the pipe line 1.

At the lower end of the shell is the apron 8 threadedly engaged at itsupper end into the lower end of the sleeve 9 which extends downwardlyfrom the lower end of the shell 4. Interposed between the upper end ofthe apron 8 and the lower end of the shell fl is the bottom wall Hihaving a pair of threaded openings Ill2 therein into which arethreadedly engaged the short tubular cages l3 and M to accommodate theball valves 55 and !3, respectively. Each of these tubes it and M hasopenings I1 therein at its upper end a stop pin it to preventdisplacement of the corresponding balls IE or Hi. The top side of thiswall Hi has the diametrically disposed groove 59 therein for receivingthe lower portion oi the partition 2!. This partition 2| in the form ofa flange extending laterally from the working barrel 22 and downwardlybelow its lower end. As is clearly shown in Figure 3, the shell 4 isdivided into the sections ab and the edge portions of the flange 2iextending from each side of the working barrel 22 is disposed betweenthe opposed edges of the sections ab and these edges of both the shellsections and the partition flange 2! are welded together as at 23. Thustwo chambers, namely 24 and 25 are defined in the shell 4.

The top wall 26 for the shell 4 has its bottom side formed with thediametrically disposed grooves 21 for receiving the upper edges of thepartition flange 2| and is further formed with openings 28 to receivethe check valve shells 26 for the chamber 24 and the check valve shellsor cages 2'! for the chamber 25. These check valves are constructed thesame as the check valves l3 and M. The upper end portion of the workingbarrel 22 extends upwardly through the opening 28 in the top 26 and isinternally tapered to receive the tapered plug 29 which contains thepacking filled pocket 30 and the screw 3! operative against the same.The screw is tubular for slidably receiving the plunger rod 32 which hasthe plunger 33 at its lower end made up of a plurality of packingelements for snug wiping engagement against the inner side of theworking barrel 22. The packing compression screw 31 has the head 34which as shown in Figure 7 has the square socket 35 therein forreceiving the square block 36 on the rod 32 when the rod is loweredsufiiciently to engage the block 36 in the socket 35. When thisengagement is made the rod 32 can be rotated with the result that thepacking screw 3| is rotated and the packing 38 compressed to the desiredextent.

When it is desired to remove the plunger and the foregoing packing meanswithout disturbing the tube line 1, the plunger 33 can be moved upwardlyand by pounding against the plug 29 the entire plug in its packing glandcan be dislodged from the working barrel 22 and elevated through thetube line I.

In the operation of the pump it can be seen that on the down stroke (seeFigure 2) water moves upwardly through the skirt 8 and through the checkvalve !4 to the chamber 25 and flows into the working barrel 22 throughthe opening 3?, as water in the working barrel 22 below the plunger 33is forced out through the openings 38 and upwardly through the chamber24 to the tube line 1 by way of the check valves 26. Reverse actiontakes place when the plunger is moved in an upward direction.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

In a pump of the character described, a shell, a bottom plate in theshell having valved ports and a groove therein, a top plate in the shellhaving an aperture and a groove and valved ports therein, a workingbarrel in said shell having an upper end extending through the aperturein said top plate, a partition in said shell extending diametricallyfrom opposite sides of said barrel and below the lower end thereof, saidpartition having top and bottom ends mounted in the grooves of the topand bottom plates, respectively, and dividing the shell into a pair ofcompartments, a packing gland in the upper end of said working barrel, aplunger in said working barrel, and a rod connected to said plunger andextending through said gland, said barrel being provided with aperturesin the upper and lower ends thereof the apertures in the upper endcommunicating With one of said chambers and the apertures in the lowerend communicating with the other of said chambers.
